摘要：

A magnon-phonon interaction model is set up in a two-dimensional ferromagnetic compound square-lattice system. By using Matsubara Green function theory we have studied the magnon damping of the system, calculated the magnon damping on the main symmetric lines in the Brillouin zone, and discussed the influences of the temperature on the magnon damping. The results show that the coupling of the optical-mode phonon and magnon plays an important role for the magnon damping, especially the longitudinal optical-mode phonon contributes the most for the magnon damping.
